<div class="textblock"><p>This file contains usb Microphone application related functions. </p>
<p>This example only provides a reference as to how an isochronous transfer related application can be written. This example emulates a microphone and when connected to a Windows PC will be detected as a Microphone and if we open sound recorder and start recording data, this example sends data on isochronous endpoint and the PC can store this data. Noise will be heard when this data is played on the PC.</p>
